为使尚处于较粗糙状态的基层达到涂饰要求，须用腻子再批嵌平基层，经打磨后

In order to make the base layer in a relatively rough state meet the finishing requirements, the base layer must be flattened with putty. After sanding, it will become a smooth and smooth surface. <br>The putty of the outer wall of the first road is roughly leveled to provide a smooth construction surface, fill in the micro cracks and prevent the coating from cracking. This putty is mainly composed of polymer resin and inorganic silicon, and the filler is heavy calcium carbonate and quartz sand with coarser particle size. The construction method is divided into 2-3 times. According to the blocks separated by the division seam, scrape the thick elastic waterproof putty one by one. Use an aluminum alloy scraper equal to the length and width of the block to check the flatness of the putty film vertically and horizontally. The second putty should be done after the first putty has dried. The function of the third pass is to fill the rough surface of the rough putty to make the surface smoother and denser, and the split seams should be repaired in place. <br>Erdao exterior wall fine batch putty is a special polishing putty for fluorocarbon coatings. It is formulated with special resin high-quality pigments and high-performance additives. The function of polishing putty is to form a fine and dense putty film on the surface layer, making the coating film plump during spraying, waterproofing and preventing a large amount of primer from penetrating the base layer, saving the amount of paint used. Use polished putty to thinly scrape the base layer 1-2 times, and dry it for 4 hours for each application, and finely grind it with 600# sandpaper until it feels smooth and smooth.

In order to make the grass in a rougher state to meet the coating requirements, putty must be used to flatten the grass, after polishing, into a smooth, smooth surface.<br>The headway outer wall putty is mainly roughly flat to provide a flat construction surface layer, fill the fine cracks, prevent the coating cracking. This putty is mainly made of polymer resin and inorder silicon, and the filler is heavy calcium carbonate and quartz sand with a coarser particle size. Its construction method is divided into 2-3 times, according to the block sewn out of the sub-section, batch by block scraping rough elastic waterproof putty, respectively, with the block length, width and equal aluminum alloy scraper vertical, horizontal inspection of the flatness of the putty film. The second putty is to be carried out after the first putty is dry. The role of the third time is to fill the rough surface of the rough putty, so that the surface is more flat, dense, the split seams should also be patched in place.<br>Two outer wall batch putty for fluorocarbon coating special polishing putty, it uses special resin high-quality pigments and high-performance additives from the combination. The role of polished putty is to form a delicate and dense putty film on the surface layer, so that the coating film is full, the same waterproof and prevent a large number of primers seeping into the base, saving the use of paint. Use polished putty to scrape the base thin 1-2 times, each construction needs to be dried for 4 hours, with 600 sandpaper finely ground to feel smooth and smooth.

In order to make the base course which is still in a rough state to meet the painting requirements, it is necessary to use putty to embed the base course again. After grinding, it will become a flat and smooth surface.<br>The first course of external wall putty is mainly roughly leveled to provide a smooth construction surface, fill in micro cracks and prevent coating cracking. The putty is mainly composed of high molecular resin and inorganic silicon, and the filler is heavy calcium carbonate and quartz sand with coarse particle size. The construction method is divided into 2-3 times. The thick elastic waterproof putty is applied to the blocks separated according to the division joints. The flatness of the putty film is checked longitudinally and horizontally with aluminum alloy scraping ruler equal to the block length and width. The second putty shall be carried out after the first putty is dried. The function of the third time is to fill the rough surface of the coarse putty, so that the surface is more flat and dense, and the grid joint should be repaired in place.<br>The second layer of fine putty for external wall is a special polishing putty for fluorocarbon coating. It is made of special resin, high-quality pigment and high-performance additives. The function of polishing putty is to form a fine and dense putty film on the surface layer, which makes the coating film full during spraying. It is also waterproof and prevents the primer from penetrating into the base layer in large amount, thus saving the amount of coating. The base course shall be thinly scraped with polishing putty for 1-2 times, and each construction shall be dried for 4 hours, and shall be finely ground with 600 sandpaper until it feels smooth and smooth.<br>
